Description

Technical Field

[0001] This utility model relates to the field of steel structure wind tower technology, and in particular to a steel structure connection node for a steel structure wind tower. Background Technology

[0002] As a crucial component of clean energy, wind power generation is seeing its tower structures evolve towards higher and stronger designs. Steel-structured wind towers are widely used due to their high strength and rapid construction. Traditional wind tower steel structure nodes often employ planar truss forms, where steel structural members are directly welded or bolted together. However, this structure shows increasing instability and inadequacy when facing ever-increasing wind loads, especially dynamic alternating loads. The column base of the steel structural members is prone to local buckling under enormous bending moments, and stress concentration at the nodes is significant, posing safety hazards. Furthermore, existing wind tower steel structure connection nodes still suffer from low connection strength, failing to effectively prevent tower swaying.

[0003] Therefore, it is essential to invent a steel structure connection node for a steel wind tower. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a steel structure connection node for a steel wind turbine, solving the issue that existing wind turbine steel structure connection nodes still suffer from low connection strength and cannot effectively prevent wind turbine swaying. A steel structure connection node for a steel wind turbine includes steel structural uprights, an upright connecting frame, a supporting intermediate support rod, a pressure-bearing inclined connecting frame, and a support rod connector. The upright connecting frame is fixedly installed between each group of steel structural uprights, and the supporting intermediate support rod is located in the middle position inside multiple groups of steel structural uprights. The pressure-bearing inclined connecting frame is fixedly installed between the steel structural uprights and the supporting intermediate support rod. The support rod connector is fixedly installed at one end of the supporting intermediate support rod.

[0005] The steel structure upright includes a column base, connecting flanges, intermediate reinforcing filler, and connecting bracket mounting base. The connecting flanges are fixedly installed at both ends of the column base, and the intermediate reinforcing filler is fixedly installed inside the column base. The connecting bracket mounting base is fixedly installed on the outer wall of the column base.

[0006] The supporting intermediate support rod includes a vertical support rod, an extension support arm, a force-bearing connecting seat, and mounting holes. The extension support arm is fixedly installed on the outside of the vertical support rod, and the force-bearing connecting seat is fixedly installed on the top of each set of extension support arms. The mounting holes are opened at both ends of the vertical support rod.

[0007] The steel structure uprights are divided into groups of three, and each group is connected and fixed by connecting flanges and bolts. The intermediate reinforcing filler is a metal tube with the same thickness as the upright base, and the two ends of the intermediate reinforcing filler at the contact position with the upright base are connected together by welding. The connecting frame mounting base is composed of several metal plates that can connect the upright connecting frame and the pressure-bearing inclined connecting frame, and are oriented in different directions as needed.

[0008] The number of intermediate support rods is the same as that of the steel structure uprights; each set of intermediate support rods is connected together by a support rod connector; the vertical support rod is a solid metal rod with two sets of blind holes for mounting, which allow the support rod connector to slide inwards; the extended support arm consists of three sets of outward-extending metal rods that support three sets of load-bearing connecting seats; the load-bearing connecting seats consist of three steel metal plates and can be connected to the steel structure uprights via a pressure-bearing inclined connecting frame.

[0009] Compared with the prior art, the present invention has the following beneficial effects: The steel structure uprights of this utility model have an internal column base connected end to end by connecting flanges to form the main body of the tower, which directly bears the main vertical load. The connecting frame mounting base on the outer wall provides the installation foundation for the upright connecting frame and the pressure-bearing inclined connecting frame, thereby effectively transferring the external load to the entire node system. At the same time, the internal intermediate reinforcement filling ensures the local stability and load-bearing capacity of the column base itself.

[0010] The present invention supports the intermediate support rod, with its vertical support rod serving as the main central pressure-bearing component. The force-bearing connecting seat at the end of the extended support arm on the outside is connected to the steel structure upright through the pressure-bearing inclined connecting frame, thereby converging and bearing loads from multiple directions. At the same time, the mounting holes at both ends of the vertical support rod are connected to the upper and lower sections through the support rod connector, ensuring the continuity and stability of the central force transmission path.

Detailed Implementation

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0016] As attached Figure 1 To be continued Figure 3 As shown.

[0017] This utility model provides a steel structure connection node for a steel structure wind tower, including a steel structure upright 1, an upright connecting frame 2, a supporting intermediate support 3, a pressure-bearing inclined connecting frame 4, and a support connecting body 5. The upright connecting frame 2 is fixedly installed between each group of steel structure uprights 1, and the supporting intermediate support 3 is located at the middle position inside multiple groups of steel structure uprights 1. The pressure-bearing inclined connecting frame 4 is fixedly installed between the steel structure upright 1 and the supporting intermediate support 3. The support connecting body 5 is fixedly installed at one end of the supporting intermediate support 3.

[0018] The steel structure upright 1 includes an upright base 11, a connecting flange 12, an intermediate reinforcing filler 13, and a connecting frame mounting base 14. The connecting flange 12 is fixedly installed at both ends of the upright base 11, and the intermediate reinforcing filler 13 is fixedly installed inside the upright base 11. The connecting frame mounting base 14 is fixedly installed on the outer wall of the upright base 11.

[0019] The supporting intermediate support rod 3 includes a vertical support rod 31, an extension support arm 32, a force-bearing connecting seat 33, and a mounting hole 34. The extension support arm 32 is fixedly installed on the outside of the vertical support rod 31, and the force-bearing connecting seat 33 is fixedly installed on the top of each set of extension support arms 32. The mounting hole 34 is opened at both ends of the vertical support rod 31.

[0020] The steel structure uprights 1 are divided into groups of three column bases 11, and each group is connected and fixed by connecting flanges 12 and bolts. The intermediate reinforcing filler 13 is a metal tube with the same thickness as the column base 11, and the two ends of the intermediate reinforcing filler 13 and the column base 11 at the contact position are connected together by welding. The connecting frame mounting base 14 is composed of several metal plates that can connect the upright connecting frame 2 and the pressure-bearing inclined connecting frame 4, and are oriented in different directions as needed.

[0021] The number of intermediate support rods 3 is the same as that of the steel structure uprights 1; each set of intermediate support rods 3 is connected together by support rod connectors 5; the vertical support rod 31 is a solid metal rod, and the mounting hole 34 is a set of two blind holes, the mounting hole 34 can slide inward to install the support rod connector 5; the extended support arm 32 is a set of three outwardly extending metal rods, and supports three sets of force-bearing connecting seats 33; the force-bearing connecting seat 33 is a set of three steel metal plates, and the force-bearing connecting seat 33 can be connected to the steel structure uprights 1 through the pressure-bearing inclined connecting frame 4.

[0022] In this steel structure wind tower connection node, the outer steel structure uprights 1 serve as the main load-bearing skeleton. Through the connecting frame mounting base 14, they form a horizontally stable frame with the upright connecting frame 2. Simultaneously, the load-bearing inclined connecting frame 4 transfers external wind loads and other lateral forces to the supporting intermediate struts 3 at the core of the structure. This design cleverly transforms the bending moment acting on the steel structure uprights 1 into the axial force of the load-bearing inclined connecting frame 4, achieving effective force decomposition and transmission.

[0023] At the structural center, the intermediate support rod 3 serves as the force-bearing hub. Through the force-bearing connecting seat 33 at the end of its extended support arm 32, loads from all directions are gathered, with the axial pressure primarily borne by its vertical support rod 31. The upper and lower intermediate support rods 3 are continuously connected to the support rod connector 5 via mounting holes 34, forming a continuous structural force transmission path. Simultaneously, the steel structure uprights 1 enhance local stability through their internal intermediate reinforcing filler 13 and ensure vertical load transmission through the end connecting flanges 12. Ultimately, they work in conjunction with the central support system to form a spatial force-bearing system with high stiffness and stability.

[0024] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
